How to fix?

Upgrade knex to versions 0.6.23, 0.7.6 or higher.

Overview

knex is a batteries-included SQL query & schema builder for Postgres, MySQL and SQLite3 and the Browser.

Column names are not properly escaped in the postgreSQL dialect. This may allow attackers to craft a query to the host DB and access private information. Writing the following code:

var query = knex.select('id","name').from('test')
console.log(query.toSQL())

Has the following result:

{ method: 'select',
  options: undefined,
  bindings: [],
  sql: 'select "id","name" from "test"' }
